The primary purpose of using a conditioner is to add moisture and manageability to the hair. Conditioners are formulated to improve the hair's texture, making it smoother and easier to manage, especially for hair that is dry, damaged, or frizzy. They work by coating the hair strands, which helps to reduce friction, enhance shine, and provide hydration. By sealing in moisture, conditioners also help to prevent breakage and split ends, leading to healthier-looking hair.

The other choices each serve different functions in hair care. Cleansing the hair is the main role of shampoos, which remove dirt, oil, and product buildup. Protecting from heat damage is a specific function of heat protectant sprays or serums rather than conditioners alone. Coloring the hair is done using hair dyes or tints, which is unrelated to the moisturizing and conditioning functions provided by a typical conditioner. Understanding the specific purpose of each product in a hair care routine is key to maintaining healthy hair.
